Eventserver: broadcast HTML(5) server-sent events with JSON

Disclaimer: I'm the original author of eventserver and an employee of Shine Technologies. These are my thoughts, I'm not speaking on their behalf, yadda yadda yadda.

I wrote this over the course of a couple of hours yesterday morning based on thoughts I'd been having for a few weeks about HTML(5) server-sent events and the possibilities that come with it.

eventserver effectively listens on two ports: a "publisher" port and a "subscriber" port. The subscriber port implements the interesting bits of the server-sent events working draft. The "publisher" port simply accepts (JSON) messages over HTTP. These messages are then forwarded to all connected subscribers using the server-sent event protocol.

The server itself is written in NodeJS, messages are not stored, and things like Last-Event-ID are not (yet?) implemented. Just a toy for now, but perhaps an interesting one all the same!
